 Glide ratio is very dependent upon the type of prop and configuration of
 the prop.
 
For example:
 
 IVP with non-feathering propeller: fine pitch 7.7:1 coarse pitch 15:1
 
 IVP with feathering propeller: 18:1
 
 There is a big difference as you can see. If this is to figure a glide
 ring, I would be very
 
 wary of putting anything but worst case as could lead to an airplane
 ending up short of
 
 the landing area.
